[0028] Embodiment 1
[0029] As Figures 1 to 5 shown, a relay shell with a dustproof cover includes a shell body 1 and a dustproof cover 12, the side of the shell body 1 is provided with a line hole 2, the top of the shell body 1 is provided with a mounting hole 3, the shell body 1 is provided with a turning path, the dustproof cover 12 moves along the turning path and flips to make the dustproof cover 12 have a first state of covering the mounting hole 3 and a second state of flipping open, the shell body 1 and the dustproof cover 12 are provided with a clamping cooperation structure to lock the dustproof cover 12 in the first state of the dustproof cover 12.
[0030] The shell body 1 is provided with the device body of the flame-retardant relay, the shell body 1 plays a protective role on the device body, the electric wire cable is inserted into the inside of the shell body 1 through the line hole 2 and is locked through the bolt 30 of the mounting hole 3 to complete the electric connection. The shell body 1 is injection molded by using the high flame-retardant grade engineering plastic alloy, and the relay shell is injection molded by using the high flame-retardant grade engineering plastic alloy. The overall flame-retardant performance of the relay shell is high.
[0031] The dustproof cover 12 of the present application is mainly used to ensure protection and dust prevention at the mounting hole 3, to avoid dust accumulation at the mounting hole 3. If there is a lot of dust at the mounting hole 3, when the bolt 30 in the mounting hole 3 is loosened, the dust may enter the inside of the relay housing from the mounting hole 3, causing the wire insulation shell to age faster and be prone to leakage. The dustproof cover 12 of the present application can avoid this situation.
[0032] The dustproof principle of the present application is that the dustproof cover 12 arranged to rotate has two states, the dustproof cover 12 is constrained and limited by the turning path, and the dustproof cover 12 is flipped when moving in the turning path. The turning path can be a guide groove, a guide rib, a variety of structure combination guide, etc.
[0033] When the dustproof cover 12 shields the mounting hole 3, it is in the first state, and the connection between the dustproof cover 12 and the housing body 1 is achieved through the clamping and fitting structure. The dustproof cover 12 has good sealing ability and is not easy to be damaged, thereby having good dustproof effect. When the dustproof cover 12 is rotated to the maximum angle, since the dustproof cover 12 of the present application is moved along the turning path and flipped, the closing operation of the dustproof cover 12 also needs the two operations to be performed together, so the dustproof cover 12 is not easy to be shaken off from the second state, and thus is not easy to interfere with the wiring operation of the relay, the operation of the bolt 30 in the mounting hole 3, etc., which is beneficial to the use of the relay.
[0034] Embodiment 2,

The top of the housing body 1 is provided with a mounting groove 4, the mounting hole 3 is located at the groove bottom of the mounting groove 4, the turning path comprises limiting grooves 5 symmetrically arranged on two opposite groove walls of the mounting groove 4, and the dustproof cover 12 is provided with limiting protrusions 13 sliding in the limiting grooves 5.
[0036] The outer end of the dustproof cover 12 is provided with an outer eave 14 perpendicular to the dustproof cover 12, and when the dustproof cover 12 is in the first state, the outer eave 14 is overlapped on the side surface of the housing body 1 on the upper side of the wire hole 2. The limiting protrusions 13 are located at one end of the dustproof cover 12 away from the outer eave 14.
[0037] The installation groove 4 is arranged so that the dustproof cover 12 can hide the interior arranged outside the housing body 1, ensuring the integrity of the appearance of the relay housing. The outer end of the eaves 14 is provided with an arc-shaped groove corresponding to the wiring hole 2. When the dustproof cover 12 is in the lower state, the eaves 14 is lapped on the upper side of the wiring hole 2, and the arc-shaped groove corresponds to the upper edge of the wiring hole 2. The clamping fitting structure realizes the locking of the dustproof cover 12 and the housing body 1, realizes the reliable dustproof of the dustproof cover 12 on the upper side of the installation groove 4, can block the upper side of the mounting hole 3, and also reduces the dust entering amount on the upper side of the wiring hole 2. The protection of the connection between the wire and the end of the wiring hole 2 is realized. The limiting convex part 13 and the eaves 14 correspond to the two ends of the dustproof cover 12 respectively, wherein the limiting convex part 13 is arranged vertically on the groove wall of the installation groove 4. The limiting convex part 13 also has two places corresponding to the two opposite groove walls of the installation groove 4.
[0038] Embodiment 3,
[0039] A relay housing with a dustproof cover, comprising a housing body 1 and a dustproof cover 12, the side of the housing body 1 is provided with a wiring hole 2, the top of the housing body 1 is provided with a mounting hole 3, the housing body 1 is provided with a turning path, the dustproof cover 12 moves along the turning path and flips to make the dustproof cover 12 have a first state of covering the mounting hole 3 and a second state of flipping open, the housing body 1 and the dustproof cover 12 are provided with a clamping fitting structure to lock the dustproof cover 12 in the first state.

The support convex part 6 is provided with a vertical groove 7 parallel to the limiting groove 5 at one end corresponding to the limiting convex part 13 to form a locking segment with the limiting groove 5.
[0041] The limiting groove 5 provides a general path for the movement of the limiting protrusion 13 of the dustproof cover 12. In this embodiment, the limiting groove 5 is a vertical groove 7, and the width of the limiting groove 5 is greater than the maximum transverse dimension of the limiting protrusion 13, so that the limiting protrusion 13 can slide in the limiting groove 5 and can also be flipped. The upper side of the supporting protrusion 6 provides support for the lower side of the dustproof cover 12. When the dustproof cover 12 is in the first state of covering the mounting hole 3, the dustproof cover 12 is arranged in the air relative to the mounting hole 3, because the mounting hole 3 is screwed into the bolt 30, the supporting protrusion 6 and the dustproof cover 12 cooperate to provide a reserved space for the upper end of the bolt 30. When the dustproof cover 12 is flipped, the dustproof cover 12 can be supported by the supporting protrusion 6 or can be directly flipped in the limiting protrusion 13 without the supporting protrusion 6.

When the dustproof cover 12 is flipped along the inclined surface 8 from the first state to the second state, the dustproof cover 12 changes from the horizontal state to the vertical state.
[0043] As a simple alternative to the above-mentioned scheme, the inclined surface 8 of the supporting protrusion 6 on one side of the vertical groove 7 is replaced by an outward convex arc surface for guiding the flipping of the dustproof cover 12.
